19 A method for charging explosives in substantially horizontal bore holes, with a loading density reduced in relation to that corresponding to the complete fill up of the bore-hole diameter with the explosive in bulk form, comprising that a charging hose with an end opening is introduced into at least one bore-hole of a blasting round, that a pumpable and coherent bulk explosive is pumped through the charging hose at a controlled rate, that simultaneous with the pumping of explosive the hose is withdrawn at a controlled rate, that the pumping and withdrawal rates are adjusted to form a coherent string exiting from the hose end opening, said exiting string only partially filling up the bore-hole diameter. An apparatus for charging explosives in bore-holes in controlled volume amount per bore-hole length unit comprises, a vessel (31) containing a pumpable and coherent bulk explosive (32), a charging hose (45) adapted for insertion into the hole-hole, a conduit (38) connecting the vessel with the hose, pumping means (33, 34) for moving the explosive from the vessel through the conduit and the hose at a controlled rate, hose moving means (44, 48) allowing forward movement of the hose and withdrawal of the hose at a controlled rate and adjusting means (34, 48) for setting the ratio between the pumping rate and the hose withdrawal rate.
